Just a ridiculous idea I pieced together this morning...
Ingredients:
Living Spell: MM3, turns your spell(s) into an ooze
Sentry Ooze: Dungeonscape, template that makes your ooze intelligent, boosts stats, grants skills and feats
Spells:
- Resilient Sphere (Wiz 4, PHB) - creates an impenetrable sphere
- create water (Wiz 0, PHB) - fills sphere with water
- water to acid (Wiz 3, Stormwrack) - as the name implies
- Manyjaws (Wiz 3, SC) - 10 sets of nibbling teeth for 3 rounds
- use CL 13
So the idea is simply thus: The ooze walks up to someone and either hits them or engulfs them, and they are subject to all the spells contained within. The results is that they are encased within a sphere of acid, being chewed to death. Hence...
The Chummaker

BAB/grapple: +9/+20

space/reach: 15/15
SA: spell effect, engulf... DC 21

Str 14, Dec 17, Con 14, Int 2, Wis 21, Cha 24
skills: open... class skills: climb, hide, listen, move silently
feats: 5 open... I would suggest at least Ability Focus to up your DC to 23
CR: 15
edit: and yes, I realize the whole things sits on a bit of a fuzzy premise that assumes the spells take effect in a specific order rather than purely simultaneously... just work with me here; but really just the sphere and any damage-over-time spell should work
edit: messed up a few calculations
